Analysis of temperature influence on the monocrystalline silicon solar cells efficiency under the south-easterly Poland conditions

Recently, solar energy conversion has become a very actual item, especially when the world faces problems of petroleum supply and there has been a growing demand for using renewable energy sources. In this situation an important question araises how to use solar energy optimally. The quantum efficiency of solar cells depends on many factors: temperature, insolation, spectral characteristics of sunlight, etc. Some of these factors may be changed during exploitation of solar systems in order to increase their efficiency. The paper reports on the influence of temperature on the work efficiency of monocrystaline photovoltaic modules in hybrid solar systems in the conditions of south-eastern Poland.
